Match the following causes with their effects of habitat fragmentation:

Geological processes = Slow alteration of physical environment Human activity = Land conversion and faster alteration of environment Reduction in total area of habitat = One of the discrete phenomena of habitat fragmentation Isolation of one habitat fragment = One of the discrete phenomena of habitat fragmentation Signup and view all the answers

Match the following phenomena with their definition in habitat fragmentation:

Reduction in total area of the habitat = Decrease of the interior: edge ratio Isolation of one habitat fragment = Breaking up of one patch of habitat into several smaller patches Decrease of the interior: edge ratio = One of the discrete phenomena of habitat fragmentation Breaking up of one patch of habitat = Decrease in the average size of each patch of habitat Signup and view all the answers

Match the following with their description in habitat fragmentation:

Habitat fragmentation = Process of dividing large and contiguous habitats into smaller, isolated patches Ecosystem decay = Result of organism's preferred environment being fragmented Speciation = Suspected to be caused by geological processes altering the physical environment Extinction of species = Caused by human activity such as land conversion altering the environment Signup and view all the answers

Match the following terms with their primary characteristics in habitat fragmentation:

Fragmentation = Emergence of discontinuities in an organism's preferred environment Population fragmentation = Result of habitat fragmentation Interior: edge ratio = Decreases as a discrete phenomenon of habitat fragmentation Patch of habitat = Gets divided into several smaller patches as a result of habitat fragmentation Signup and view all the answers

Match the following human activities with their impact on habitat fragmentation:

Land conversion = Alters the environment much faster and causes extinction of many species Habitat destruction = Leads to the emergence of discontinuities in an organism's preferred environment Urbanization = Can contribute to the isolation of one habitat fragment from other areas of habitat Deforestation = Results in reduction in the total area of the habitat Signup and view all the answers
